Flags - White Ensign
The White Ensign, at one time called the St George's Ensign due to the simultaneous existence of a cross-less version of the flag, is an ensign flown on British Royal Navy ships and shore establishments. It consists of a red St George's Cross on a white field with the Union Flag in the upper canton. The White Ensign is also flown by the Royal Yacht Squadron and ships of Trinity House escorting the reigning monarch. Royal Navy ships and submarines wear the White Ensign at all times when underway. The White Ensign may also be worn on a gaff, and may be shifted to the starboard yardarm when at sea. When alongside, the White Ensign is worn at the stern, with the Union Flag flown as a jack at the bow, during daylight hours. The White Ensign is worn at the mastheads when Royal Navy ships are dressed on special occasions such as the Queen's birthday, and may be similarly be worn by foreign warships in British waters when dressed in honour of a British holiday or when firing a salute to British authorities.
